Definitions

  • This invention relates to gaskets and in particular but not exclusively, to cylinder head gaskets for use in internal combustion engines.
  • gaskets usually comprise a body portion having apertures formed therein and reinforcing and/or supporting means for the margins of these apertures.
  • British Patent GB No. 1260236 discloses a gasket construction in which at least one aperture is fitted with a two-part reinforcement, the purpose of which is to create a two-stage, primary and secondary seal around the margin of the aperture, with the secondary seal radially outermost.
  • the aperture is for the combustion chamber of an internal combustion engine
  • the construction enables the use of an all-metal primary seal backed up by a secondary seal in which both the secondary sealing element and the gasket body material are to a large extent protected from the effects of heat and pressure in the combustion chamber.
  • FIGS. (a) and (b) are cross-sectional side view of part of a gasket constructed in accordance with the present invention.
  • a gasket comprises a flat body portion comprising two gasket facings and an inner reinforcing core, the gasket having an aperture defined therein, said aperture being provided with secondary sealing means comprising flat annuli located on opposite faces of the body portion in those regions there of surrounding and adjacent the aperture, the annuli extending into the aperture to provide annular primary sealing means radially inwardly of the margin of the aperture, characterised in that one of said annuli is folded around radially outwardly of the aperture to at least partially enclose, locate and retain a primary sealing ring radially inwardly of and relative to the margin of the aperture, said primary sealing ring comprising marginal portions of both of said annuli and a co-operating portion of said reinforcing core which projects radially inwardly of the aperture from said flat body portion.
  • the other of said annuli extends into the folded-around portion of the one annulus to form at least part of the primary sealing ring and is itself folded around the margin of the core portion which projects into the apeture.
  • the two primary sealing ring may however include a U-section metal eyelet, with the arms of the U facing radially outwardly of the aperture.
  • the reinforcing core may be of plain or pierced metal sheet.
  • the U-section metal eyelet if used, preferably encloses both the core and the margin of the other annulus which need not then be folded around the core.
  • the precise configuration adopted will reflect the strength and thickness required in the primary sealing ring, providing a relatively simple way of adjusting the performance characteristics of the latter in service. It will be appreciated that the core itself is an essential integer of the invention.
  • that face of the gasket on which the one annulus lies is used as the upper, cylinder head-contacting face, with the other face against the cylinder block.
  • the upper face has no exposed circumferential seam or joint between it and the primary sealing ring, the risk of gas leakage from the combustion chamber is minimized.
  • the other face is normally adequately protected and/or supported by the cylinder block; a circumferential seam/joint on that face represents a much lower and acceptable risk.
  • FIG. (a) is a cross-sectional side view of part of a gasket constructed in accordance with the invention and FIG. (b) is a similar cross-sectional side view of a further gasket constructed in accordance with the invention.
  • a gasket body 1 comprises a plain steel core 2 and conventional non-metallic gasket facing layers 3, 4 respectively.
  • An aperture 5 is provided, in this case for an internal combustion engine combustion chamber, (not shown).
  • the aperture is provided with secondary sealing means comprised of metal annuli 6,7 on opposite faces of the gasket body 1 adjacent the aperture 5, together with a primary sealing ring constituted in part by a folded-around portion 8 or the annulus 6.
  • the primary sealing ring is constituted by a U-section eyelet 9 and the marginal portion 10 of the annulus 7, together with the folded-around protion 8 which serves to enclose the other parts.
  • a portion 11 of the core 2 projects into the aperture 5, beyond facing layers 3, 4 and together with the abutted portion ot the annulus 7 and the eyelet 9 forms the inside of the primary sealing ring.
  • the whole assembly is retained/located by the folded-around portion 8 of the annulus 6.
  • FIG. (b) differs from (a) in that the folded back part 10 of annulus 7 is folded around a projecting portion 11 of the core 2.
  • the annulus 6 lies against the cylinder head, towards the combustion chamber.
